The conman then got into a row with the postmaster, pleading for his money back. But with the cops about to arrive, he fled the scene hugely out of pocket

"Normally there's another staff member working here with me but I was on my own that day and I was worried he would become violent."

He added: "I wanted to put the video up to warn other people about this scam in the area. My advice to others would be always keep the money in clear view and count it in clear view."

Mr Javed continued: "I used what is called a walk away technique and ignored him and pretended to call the police but when he didn't walk away I had to really call them. I noticed his English improved drastically at that point."

Posting the clip online, he wrote: "Man tries to use sleight of hand to con money from staff member. It goes wrong for the fraudster when the staff member catches him out. Fraudster runs off without his money."
